Vane Anemometer
The rotating vane anemometer are prevalent today. The fan blade rotation is sensed by a magnetic or optical pick-up and the signal is converted to a direct fpm velocity readout. Digital models have less bearing friction than mechanical vanes, allowing for accurate measurement from 50 to 6000 fpm (0.25 to 30.5 m/s). A directional arrow located on the vane head identifies the flow direction used during factory calibration and should always be pointed in the direction the airflow is travelling when used in field applications.
FEATURES
• Minimum, maximum, and averaging capabilities.
• Air temperature measurement.
• Direct conversions to cfm or m3/h by inputting the free area in square feet into the instrument.
